I want this script to only add a number to this table if its not there. How can I ensure that it wont add a number if it's only there?
numbers = {}
for i=1,10 do
local N = math.random(1,10)
table.insert(N)
end

How to check if something is already in a table?

You have to loop through the table and check if the value you are inserting is already in it, for example:
numbers = {}
for i=1,10 do
local N = math.random(1,10)
local alreadyExists = false
for _, number in pairs(numbers) do -- loop through the array
if (N == number) then -- check the array value against the new number
alreadyExists = true -- set the variable alreadyExists to true
break
end
end
if (not alreadyExists) then -- if it's not in the array already
table.insert(N) -- insert it
end
end

Why not just put an else instead of another variable line 7?

Because it's in a for loop, putting an else would place it into the table multiple times

Use another for loop to go through evey item in the table and check if it's the same as your new number
